三幸 Product Lineup

We would like to introduce the "ceramic products" handled by Sanko Co., Ltd. We offer materials such as porous and dense types of alumina and zirconia. The maximum dimensions for firing are W1000×D1000×H480. Additionally, we manufacture circumferentially processed products using dense alumina on a lathe. We have alumina purities of 92%, 96%, 99%, and 99.5%. 【Characteristics of Refractories (Alumina and Zirconia)】 ■ A lineup of materials including porous and dense types of alumina and zirconia ■ Maximum dimensions for firing: W1000×D1000×H480 ■ Zirconia bubbles are also available *For more details, please refer to the PDF document or feel free to contact us.

★Ceramic crucibles that are strong against high temperatures and corrosive environments, enabling stable material testing and firing. Our "ceramic crucibles" are ideal heat-resistant containers for use in high-temperature and corrosive environments, such as material testing, firing, and melting processes. ■Features • Excellent high-temperature resistance • Available in alumina and zirconia, primarily in porous materials • Custom shapes can be produced, accommodating small lots and prototypes ■Size: Maximum outer diameter φ●×●H×t●; minimum size is negotiable Suitable for small quantities for experiments and evaluations, allowing for flexibility. Typically, production is done using wooden molds, but there are cases where wooden molds are not required. *For more details, please feel free to contact us at the information provided below.

Our company manufactures ceramic fixtures for stabilizing heater wires used in electric furnaces and heat treatment equipment. We use heat-resistant materials primarily based on alumina to prevent misalignment and breakage of the heater wires. The shapes can be customized according to the application, and we offer optimal designs based on the diameter and arrangement of the heater wires, including groove shapes, hole processing, and stepped designs. We are also flexible in accommodating small lots and prototypes. ■ Features • Stable holding power even at high temperatures • Prevents misalignment and breakage of heater wires • High insulation properties, making it an ideal alternative to metal fixtures • Custom shapes available according to application We can handle small quantities for experiments and evaluations with agility. Typically, production is done using wooden molds, but there are cases where wooden molds are not required. *For more details, please feel free to contact us at the information provided below.

Our company manufactures specialized jigs to stably support heat transfer tubes used in high-temperature processes such as firing furnaces and heat treatment furnaces. We use heat-resistant ceramics like porous alumina and zirconia, which provide dimensional stability and corrosion resistance that cannot be achieved with metals. We can prevent bending of the heat transfer tubes, ensure uniform temperature within the furnace, and propose shapes tailored to on-site challenges. We also accommodate custom manufacturing and small lots, providing support from material selection based on application. ■ Features • Made of heat-resistant ceramics that are less prone to deformation in high-temperature environments • Reduces temperature unevenness in the furnace by providing stable support for heat transfer tubes • Ensures insulation and corrosion resistance, which are difficult to achieve with metals • Supports custom shapes according to application (grooved shapes, stepped designs, hole processing, etc.) • Can be manufactured without drawings (from hearing to design) We can be flexible with small quantities for experimental and evaluation purposes. Typically, we use wooden molds for production, but there are cases where wooden molds are not required. *For more details, please feel free to contact the following address. Sankou Co., Ltd.

Our company recommends the "Porous Ceramic Crucible" for the sintering of powder materials. Unlike conventional dense crucibles, which tend to trap gas during the process, the porous structure allows for stable processing. The shapes can be freely customized, including square, round, and deep types, and we can accommodate small lots and prototypes. ■Features • The porous structure allows for good gas escape, reducing firing unevenness. • Ideal for debinding processes and material treatments that generate gas. • Maintains shape stability even at high temperatures and exhibits excellent thermal shock resistance. • Material selection according to application, such as alumina, is possible. • Custom shapes available, including square, round, and deep types. We can handle small quantities for experiments and evaluations with flexibility. Typically, production is done using wooden molds, but there are cases where wooden molds are not required. *For more details, please feel free to contact the following address. Sankou Co., Ltd.
